View Full Version : SR20DET Running REAL Rich

I have replaced the heat temp sensor, checked the MAF and changed the fouled plugs. but for some reason the car is still dumping fuel and running really rich. If I get the car up to speed and keep it in boost it will run with no problems. but when the engine is not under a load it will stall and then not crank back. The original problem was it would not idle long enough to get the engine hot - therefore I checked and replace the heat temp sensor, checked and replaced the fouled plugs. I am almost certian that the MAF is working. The only other thing that I can think could be a problem is an O2 sensor - although functional - may be covered in soot and not reading.

Opinions?

Thanks

What modifications have been done if any? s13 or s14sr? Check your injectors make sure they click and that they are not stuck opne. Also check to make sure the little o-rings or grommets are intact they could be leaking fuel from the rial rightn into the cyclinders.

I'll take another look but we have checked the injectors.

Holy god that car is modded.

Did you do all of it yourself, or buy it off someone?

EDIT:

Just saw you are running ACT HDSS with that setup.......how in God's name is it not slipping? I was (sometimes) slipping that same clutch kit with only 300 ft-lbs at the wheels......

I did some, I had some done. I did not buy it that way. As for the clutch it does not slip at the current whp but when it was being tuned it started slipping resulting in the hp it has rather that what it is capible of having.
